Socket mounted AirLoc Wedgemount® Precision Levelers were developed for customers whose machines have a closed machine foot without the possibility of tightening a fixing screw. To fix the AirLoc socket Wedgemount® Precision Levelers only a blind thread is necessary in the machine foot. A sleeve is screwed in there and the leveler is simply mounted on it. This creates a strong and secure connection between Wedgemount® Precision Leveler and machine foot. And of course the levelling capability remains completely intact. Also the spherical seat variant for unevenness of up to 3° can be reliably compensated.
